Filter by:CXCR4 inhibition may represent a new therapeutic strategy in acute leukemia (AL) patients, not only by increasing chemosensitivity but also by preventing relapse of the disease by disruption of the interaction of residual leukemic cells with the bone marrow niche. Radiolabeled CXCR4 ligands have been developed for PET imaging (68Ga-PentixaFor; INN: Gallium (68Ga) boclatixafortide) and radioligand therapy (RLT) ([177Lu]Lu-PentixaTher/[90Y]Y-PentixaTher). [177Lu]Lu and [90Y]Y-PentixaTher have been tested in three multiple myeloma patients in named-patient use with a remarkable efficacy in 2 patients (Herrmann, 2016). Moreover, feasibility of CXCR4 PET imaging in AML was reported, providing a framework for future theranostic approaches targeting the CXCR4/CXCL12-defined leukemia-initiating cell niche (Herhaus, 2016). Here a Phase I/II study to determine maximal tolerated dose (MTD) of a RLT using [177Lu]Lu-PentixaTher in relapsed/refractory AL was designed. This will be a standard phase I/II 3+3 dose escalation study. Five dose levels will be tested, so 6 to 21 patients have to be included in the study.
The purpose of this study is to test whether the combination of the drugs called tacrolimus (Tac), methotrexate (MTX) and new dosing strategy of another drug called (rabbit Anti-thymocyte Globulin [ATG]) will help prevent the development and/or improve severity of acute and/or chronic GVHD.
Graft-versus-host disease (GVHD) is an important complication after transplantation, with an incidence of 40-60%, which can increase non-relapse mortality if poorly controlled. At present, the standard prophylaxis for GVHD is cyclosporine combined with methotrexate. However, calcineurin inhibitors (CNI) can cause some vital side effects, which are not tolerated by some patients. Therefore, this study aims to explore the safety and efficacy of Sirolimus in combination with Abatacept and Mycophenolate Mofetil for the prophylaxis of GVHD in patients with haplo-HSCT who are intolerant to calcineurin inhibitors.
In an effort to reduce graft versus host disease (GVHD) and enhance graft versus leukemia (GVL) effect post allogenic hematopoietic stem cell transplantation (AHSCT), recent research has focused on host immune cell depletion. Frame shifting anti-thymocyte globulin (ATG) backwards to earlier days before days 0 can result in deeper host and less graft T-cell depletion, leading to better immune reconstitution. Preliminary data where 80% of the ATG dose is given on days -6,-5,-4 and 20% given on day -1, showed effective prevention of severe acute GVHD, chronic GVHD and favorable early immune reconstitution. We hypothesize that our 2 step ATG dosing platform when combined with standard tacrolimus and mini methotrexate can prevent grade III-IV acute GVHD and chronic GVHD, resulting in improvement of GVHD/relapse free survival at one year post transplant.
A research investigation into the efficacy of digital Polymerase Chain Reaction (dPCR) for monitoring measurable residual disease (MRD) during allogeneic hematopoietic stem cell transplantation, with a focus on predicting relapse in patients diagnosed with leukemia, myelodysplastic syndromes (MDS), and related hematological conditions.
The purpose of this study is to learn more about LP-118 (an experimental drug) and its side effects and decide on acceptable doses. The purpose of this study is to determine if LP-118 can be given safely with another medicine called ponatinib, that is FDA-approved for the treatment of acute lymphoblastic leukemia.
This post hoc analysis included patients with acute leukemia who underwent allo-HSCT at the First Affiliated Hospital of Zhejiang University School of Medicine and Ruijin Hospital Shanghai Jiaotong University School of Medicine. Patients and their donors were assessed for eligibility to join this study. The inclusion criteria were: (1) age ≥ 5 years; (2) diagnosis of acute leukemia including acute myeloid leukemia, acute lymphocytic leukemia, and mixed phenotype acute leukemia; (3) patients attained complete remission (CR) and achieved full engraftment with 100% donor chimerism following allo-HSCT; (4) telomere testing was conducted on peripheral leukocytes of donors before granulocyte colony-stimulating factor (G-CSF) mobilization, and the results were obtained. Written informed consent was obtained from all included patients and their donors, and the study was conducted in compliance with the Declaration of Helsinki. Ethical approval was approved by the ethics review committee of the First Affiliated Hospital of Zhejiang University School of Medicine.
Letermovir is approved for the primary prevention of Cytomegalovirus (CMV) reactivation and infection in hematopoietic stem cell transplant recipients. Letermovir may be beneficial in other clinical presentation where CMV reactivates and may alter clinical outcomes. Recently Chimeric Antigen Receptor (CAR) T cells have been used for the treatment of refractory acute leukemia and B cell lymphoma. Reactivation of chronic viral infections, in particular those belonging to the Herpesviridae family can therefore be observed following CAR-T cells treatment.According to first reports, Cytomegalovirus seems to be the main virus detected. Uncontrolled CMV reactivation leads to CMV disease requiring the use of antiviral drugs associated with either hematological toxicity (ganciclovir) or renal toxicity (foscarnet) and is usually associated with poor outcomes. In addition, CMV interplays with the immune system and decreases the immunosurveillance of tumor cells and facilitates the growth or reactivation of other opportunistic infections. Therefore, CMV reactivation could also impact the outcome of CART cells treatment by increasing the existing risk of opportunistic infections in CART cells recipients and thus by increasing morbidity, length stay or require intensive care. Imbalance of the immune system usually correlates with reactivation of persistent virus like Torquetenovirus (TTV), redondovirus or pegivirus found more frequently in Hematopoietic stem-cell transplantation (HSCT) patients or patients requiring intensive care. Whether reactivations of those persistent viruses are associated or precede CMV reactivation deserve careful investigation to identify as early as possible patients at high risk and who could benefit from antiviral preventive treatment. The objective of this trial is to determine the incidence of CMV reactivation within 3 months after infusion of CAR-T cells in CMV seropositive patients with refractory acute leukemia or B-cell lymphoma.
- Goal: This study is a randomized phase II interventional study. The purpose of this study is to see if addition of oral rifaximin tablets during allogeneic stem cell transplant can improve the quality of gut microbiome and reduce chances of death, infections and graft versus host disease (GVHD) post-transplant. - The study objectives are as follows: - Primary Objective: To determine the impact of rifaximin on gut microbial diversity and compare it with controls. - Secondary Objectives: a. To determine non-relapse mortality at 1-year post transplant in patients who receive peri-transplant transplant rifaximin and compare it with controls. - b. To compare the incidence of severe GVHD in patients who receive peri-transplant rifaximin with the controls. - c. To determine impact of gut decontamination with rifaximin on incidence of MDR sepsis and usage of higher antibiotics (e.g. Carbapenems, colistin, tigecycline, ceftazidime avibactum and ceftriaxone-sulbactam EDTA) in first 6 months post BMT. - d. To determine the impact of rifaximin induced gut manipulation on immune reconstitution, T cell repertoire post-transplant and cytokine profile. - Exploratory objective: To use single cell transcriptomics (SCT) to identify immune cell profile in gut biopsies post allogeneic stem cell transplant whenever biopsy is done, to correlate the impact of microbiome on gut immunity. - Intervention: Tab Rifaximin 200 mg will be given orally twice daily from day -8 to day +60 of allogeneic stem cell transplant in acute leukemia patients. This will be in addition to standard of care post-transplant treatment. - Comparator Agent: Standard of care treatment including standard anti GVHD measures, antibiotic support and transfusions as needed.
Objective: To longitudinally track the dynamic changes in the survival quality of pediatric patients after hematopoietic stem cell transplantation at different time points within 1 year post-transplantation, analyze the influencing factors of survival quality at each time point, identify independent risk factors that can be intervened, provide reference for medical staff to recognize survival quality problems early, guide the dynamic management of clinical survival quality, and formulate continuation care management plans. Methods: This study adopted a repeated measurement study design. A total of 250 pediatric patients who underwent hematopoietic stem cell transplantation in three tertiary hospitals in Guangdong Province from August 2023 to December 2025 and met the research standards were selected as the research subjects. The "Childhood Health Assessment Questionnaire Transplant Module 3.0 Chinese Version" was used to evaluate the survival quality of the patients at six time points: 1 week before pre-treatment (T0), the day of stem cell infusion (T1), 1 month (T2), 3 months (T3), 6 months (T4), and 1 year (T5) after transplantation. Statistical methods for repeated measures were used to analyze the relevant information, and mixed-effect linear models were used to analyze the influencing factors of survival quality at the six time points, and to identify independent risk factors.
